Since we are going to do filter deletion at multiple places in the
upcoming patches, add a function that does the deletion.  Future patches
add more code into this function.

Since we are passing the address of the filter base to free the
entire filter structure, add a comment to make sure that the base
is always at the beginning of the structure.
